If you could be transported back to Africa as it was 30 million years ago, almost none of the wildlife would look familiar. But if you came back 10 million years later, many of the animals would resemble the ones that live there today.
What happened in that intervening 10 million years is shrouded in mystery. But, as NPR's Richard Harris reports, scientists working in Ethiopia have found a trove of fossils that sheds light on that time. Inside seemingly ordinary gullies, the researchers have uncovered a range of animals, from tiny, extinct relatives of elephants to huge, rhino-like creatures. Their findings appear this week in the journal Nature.
